CONCRETE STRUCTURE.

Application filed December 31, 1924. Serial No. 759,207.

cludes the provision of'a base member pri marily separate from, .but adapted to be readily attached to, a Vpile of concrete or wood or other material of such form, construction and arrangement as to `facilitate the use ofwater to sink the columnar member to which it is attached andto facilitate the gravitation of the latter.

As hereinafter described; my improved base member may be formed of concrete molded in a pyramidal form, imbedding a water jet tube extending from the apex of the pyramid, which is used up side down, to an uppercorner thereof, andhaving a` bayonet slot or other detachably connecting means for temporarily engaging a water supply conduit, and also'having iinbeddedtherein, fieXible metalA hangers having their free ends projecting therefrom, primarily in such position that the lower end of the columnar member may be readily inserted between said hangers; the latter being thenA bendable to then engage metal studs or hooks projecting from the columnar member; whereby, such a base member may be permanently attached to a .columnar member and form a footing for the latter after it has Abeen sunk in the soil. My invention includes an improved suspension clamp which supports said water conduit and is provided with means for detachably connecting it with the columnar member; whereby the latter may be suspended, lifted and lowered, as hereinafter described.

My invention includes the various novel features of construction, arrangement and procedure hereinafter more definitely specified.

In the drawings Fig. I is a fragmentary n' -side elevation of a columnar `memberand suspension clamp carrying an adjustable waterconduit embodying my invention.

Fig. II is a plan view of thesuspension clamp and its appurtenances shown in Fig. I.

Fig. III is a .side elevation of a base mem- Fig. yV is a fragmentary sideelevation of said columnar member and conduit shown in Fig. I, with the'base member shown in Fig.

III connected therewith.

Fig. VI is a plan view of the assembledy partsshown in Fig. V.

' In said figures; the base lmember 1 is conveniently formed of a concrete aggregate, or other plastic material, molded or cast in pyramidal form, imbeddiiig the water jet tube 2 having its lower end y3 extending from the apex of the pyramid and having its upper end lprojecting from an upper corner of said base. As indicated in Figs. III to VI inclusive; said jet tube end 4 carries a cross bar 6 forming detachably connecting means for temporarily engaging the oppositebayonet slots? iii the water supply conduit 8,. as shown in Fig. V. Said base also has imbedded therein'a circular series of flexible metal hangers 10 having their lower ends 11 bent toward each other, for better engage-y ment with the material of said base 1 and having their free endsprojecting therefrom primarily in such position,- as exempli# fiedy in Fig. III, that the lower endV of the j columnar member 12 may be readily inserted `between said hangers.

Each of said hangers has a perforation 13, near its upper end, adapted to register with metal studs 14: which are imbedded in and project from said columnar member 12 and both said hangers and said studs are bendable to interengage them 'as indicated in Fig. V; whereby such a base member 1 may be permanently attached to such a columnar member 12. l I find it convenient to reinforce said base member 1 by an annular member 16, conveniently formed of ai steel bar, encircling the lower ends of said hangers. However, other reinforcing means may be employed.

Said columnar member 12 is indicated as a molded concrete pileor column provided with metallic reinforcements including longitudinal members 17 encircled by transverse annular members 18. However, I donot desire to limit myself to such construction, as inyinvention is, of course, applicable to piles vor columns of wood oi other material.

I iind it convenient to suspend the conl 't8 l l b 112b fl o ui anc co.umnai mem ei y means o a suspension clamp conveniently consisting of a metal plate 20 having the bearing 21 for said conduit 8 and provided withthe swivel suspension eye 22 for engagement with y lumnar member 12 and opposed by the U-bolt which has its opposite ends extending through holes 2G in said plate 2O and provided with nuts 2i'. rl`he ll-bolt 29 is hingedly connected with said plate 2O by bearings and has its opposite free ends extending through the yolie bar 3l and provided with nuts 32; whereby -said bolt 25 may be clamped toward the pendent portion 24: of said plate 2O to grip the upper end of said columnar member` 12'so that it may be raised, suspended and lowered by manipulation of the cable 2b.

Said conduit 8 is provided with the clamp bearing Bfl; for the hand lever 35 which may be supplemented by the removable tubular extension 36; whereby said conduit may be raised. and lowered and turned. As shown in Fig. l; the bayonet slots in the lower Vend of vsaid conduit 8 are in alinement with the cross bar 6 in the upper end e of the water jet tube 2, so that when said conduit is lowered into said tube end-4, it may be engaged therewith'by turning said lever 35 in the directionof the arrowv indicated in Fig. Il. Said lever extension 36 is provided with the *lexible connector 37 for detachable connection with the projection 38 on said plate 20; whereby said conduit S may be detachably detained in interlocled engagement with said cross bar 6 of said jet tube 2.

rllhe apparatus above described may be used as follows: rlhe suspension clamp including said plate 20, is fitted to a selected columnar member 12, as indicated in Fig. l; and firmly secured thereon by tightening the nuts 82. Said columnar member 12 is then provided `with a base member 1 fitted thereon to the position shown in Fig. V. and with the conduit 8 in connection with the jet tube 2, as' indicated in that ligure. Thereupon; water under 'pressure may be supplied through said conduit o to displace the sandy soil 210 beneath said base 1 while the latter and the columnar -member 12 connected therewith yare lowered by slachening the cable Such operation is continued until the columnar member 12 has sunk to the desired position. Thereupon, the flexible connector 87 is disengaged from the projection 38 and said hand lever 85 turned in the direction opposite to the arrow in Fig. ll, thereby returning the conduit 8 to the position shown in Fig. l in which it may be withdrawn upwardly from the upper end l of the jet tube 2 by means of the suspension clamp plate 20 which is released from the colun'mar meniber 1 2 by reverse rotation of the nuts 32 so that the suspension clamp may be uplifted'by the cable 23 and applied to another column ar member7 and the operation repeated.

So far as lf am aware, itis original with l. A base member for a columnar element varranged to Vfacilitate sinking thereof by water jetting and adapted to forma perma-r nent footing for said element, including a molded concrete body of pyramidal form havin g a metallic water jet passageway imbedded in said concrete and extending from the apex thereof to a corner thereof; and means arranged to attach said base member to said columnar element, including an annular series of flexible metal hangers projecting from said base member, and each having one end imbedded in said concrete; and an annular metallic member also imbedded in'said concrete and interlocled with the ends of said hangers. v

2. A base member for a columnar element,V including a body formed of'co'ncrete molded in a pyramidal form, imbedding a water jet. tube extending from the apex ofthe pyramid to a corner thereof; said cornerend of said tube having bayonet slot connecting means arranged to temporarily engage a water supply conduit; said body Vhaving imbedded therein' llexible metal hangershaving free ends projecting from the surface thereof opposite to said apex; said free ends being perforated and'arranged vto engage lateral projections extending from said columnar element; whereby said base member may bepermanently attached to a columnar element to facilitate sinking thereof by means of water j ettin g and to form a footing for said element after it has been sunk. f Y

3. The combination with a columnar element having lateral projections adjacent to the lower end thereof; of a primarily separate precast base member comprising a concrete body of pyramidal form having metallic hangers projecting therefrom and primarilyV detached from, but arranged to permanently engage the projections on said columnarv element; and said base having a metallic water jet tube imbedded therein extending from the apex to one corner thereof; and said tube having means arranged to detachably connect it Y with a rotary water conduit. L

4. The combination with a baseof down-l wardly converging form having a water' jet passagewayY from its lower apex to its upper surface; of a water couduithavingmeans arranged for detachable connection with said base and passageway; and an adjustable suspension clamp including a bearing Support for Said conduit7 arranged to permit rotary and axial movement of Said conduit. therein and SoreW bolts arranged to detachably clamp a columnar element in cooperative relation with Said conduit and base; and means eoop-v eratively connecting Said conduit and clamp, whereby they may be applied and removed to- `Signed my name at Philadelphia, Pennsylvania, this twenty-seventh day of December, 1924.
